To all whom it may concern:

Be it known that I, FREEBORN F. RAYMOND, 2d, of Newton, in the county of Middlesex and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Machines for Conipressing Heels, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

This invention relates to machines for compressing heels and similar articles. In machines of this nature, the removal from the compressing device of the blank operated upon has always been a difiicult matter. The need of a device which will satisfactorily perform this operation, which possesses simplicity in construction and is of such form as to require no modification of the compressing devices in its application to a machine, has long been felt.

It is the object of my invention to produce a device possessing these and other desirable attributes hereinafter mentioned.

In the preferred embodiment of my invention I provide means which permits the automatic discharge of the blank through the bottom of the die after the opeiation of compressing is completed.

A convenient form of device consists of a die bed plate which may be withdrawn from its operative position, in which it forms the bottom of the die cavity, and the blank allowed to pass or be ejected through the opening thus formed. The passage leading from this opening may be foiincd of an area sufficient to receivea blank of the largest size which is to be operated upon in the machine.

Preferably I provide the side formers or dies, which may be otherwise of a usual form, with a sufficient opening movement after the compression of the blank as to enlarge tlie die cavity sufliciently to permit the blank to pass readily from the cavity. This permits the ejection of a heel which is compressed with its smaller end at the bottoni of the die cavity.

In the machine shown I have found it convenient to give the bed plate a lateral movement and to withdraw it from beneath the compressing cavity on the side adjacent the breast section of the die.

It is desirable to provide means for feeding an uncompressed heel into the die from a point removed from the die. I secure this end by the conjoint action of the breast section of the die and the bed plate, the breast section being supported on the bed plate and movable to and from the die to feed a heel resting on the bed plate into the die between the side sections thereof, the feeding movement of the breast section preferably taking place simultaneously with the movement of the bed plate into operative position. To hold the compressed heel in the die cavity while the bed plate is being withdrawn from the bottom of the die, I may retain the breast section in its operative position until the bed plate has been moved out of contact with the heel.

I have represented the invention as applied to a machine in which the heel seat former is over the side forming section of the die and is stationary and in which the bed, side sections of the die and breast are movable towards and from the stationary die, and the sides caused to be closed as they approach the former and to be opened as they move from it. These parts, however, may have any other operative movements in relation to each other.

When the breast section is used as a feeder the uncompressed lieel enters the die cavity through its front and on a level with its bottom and the compressed heel escapes from the die cavity through its bottoni, a a course of movement for the heel which is new in compressing machines and one that permits the employnient ol' a short compressing movement of the bed and side foi-mers to the seat former, as there is no necessity of space between the top of the side foi-mers and the seat former for the placing or removal oi' the heel between them as is now customary in some types of heel compressing devices. This short movement also permits a better application of power to the compressing devices from the shaft and an increase in it as well.

It should be understood that a heel is compressed for the purpose of forming in one end of it a cavity called the seat, for shaping its sides and breast to a shape approximating that of a finished heel, for providing a firm, flat tread end, and for giving the sides a density which the heel did not before possess.

I will now describe my invention in detail in conjunction wi th the drawings, forming a part of this specification, where- A Figure I is a view in front elevation of a heel compressing machine having the features of my invention, and showing especiallyY the means for operating the side compressors and the means for moving the bed plate and the breast portion of the compressing devices. Fig. 2 is a view in` side elevation of said inacliine still further showing the construction oi said devices. Fig. 3 is a view in horizontal section of the machine taken upon the dotted line 3 3 of Fig. l, representing in plan the parts below said line. Fig. 4 is a detail view representing the compressing devices when the bed plate and breast are in compressing position. Fig. 5 is a detail view of the saine parts, showing the bed plate moved so far forward that its end is in front of the cavity of the die or mold, the breast portion of the mechanism being represented as unmoved and the compressed heel blank as having fallen, or been moved, from the compressing mechanism to the space which had before been occupied by the bed plate. Fig. 6 is a detail view of the same parts representing the breast portion of the compressing devices as moved forward onthe bed plate, and also showing an uncompressed heel blank upon the bed plate back of said breast portion of the compressing mechanism. Fig. 7 is a further view in detail representing a slight modification of the position and shape of the feed-way through which the compressed heel escapes from the compressing devices.

Referring to the drawingsz-A is a stationary cross head mounted upon the upperl ends of the rods B, of which there are four. These rods extend upward from the base() of the machine to which they are secured. The cross head has attached to it, to extend downward from its under surface, the heel seat former D, which is the upper part of the heel compressing or molding mechanism. It is vertically adjustable and is also removable, that other formers of different sizes and shapes Amay be substituted.

E is a pressure head mounted upon the rods B, to be vertically reciprocated thereon and also to be guided thereby. It is beneath the cross head A and is provided with a vertical movement towards and lfrom it by means of an eccentric e, and the pitman el, connecting the eccentric with the pressure head. The eccentric is mounted upon the shaft e2 which has suitable bearings upon the base C, and is attached to it by cap plates. The vertically movable pressure head supports all the heel compressing or molding apparatus excepting the former D, and which consists of the sections F, Fl and F2 `and the bed G. The sections F, F1 compress and shape the sides of the heel by a lateral movement upon the upper surface of the pressure head towards each other. The section F2 coperates with the sections F, F, and serves to compress and shape the breast of the heel.

The bed G forms the bottom of the compressing apparatus, holds and serves to hold the heel blank in the p compressing mechanism before it is compressed and while it is being compressed, andalso acts to compress and shape the tread of the heel during the compressing operation. The side shaping and compressing sections F, Fx are attached to and moved by slidesf, f respectively, which are held to the upper surface of the pressure head by cap plates, and are provided with closing and opening movements thereon by means oi the links f2, f3, which connect them with the stationary head A,

or with downward extending armsf, f5, solid therewith or bolted thereto. The links extend from `these arms diagonally downward and inward to the outer ends of the said slide blocks to which they are pivoted. The upward movement of the pressure head lattens the position of the links and thus causes them to move the slide blocks and the side die sections F, Fl, towards each other and against the sides of the heel blank held between them.

The breast section F2 of the die is movable horizontally between the front of the machine and the side die sections F, F1. It is mounted upon a slide plate G1, a portion of which forms the bed G of the compressing apparatus. This slide plate is mounted in the upper end of the pressure head to be moved horizontally from and towards the front of the machine. It is provided with an inward. movement by means of the cam g upon the iront end of the shaft e2, and a lever g1 pivoted at g2 to a bracket g3 attached to the pressure head, and a vertically movable slide g4 mounted in the bracket, the lower' end of which slide bears upon the edge of the cam, and the upper end of which slide is connected with the short outward extension of the lever. The upper end of the lever is connected to the slide plate by a link g5. The cam is so shaped as to move the slide plate G inward at the desired interval of time, and so that the portion of it which forms the bed of the compressing apparatus shall be moved into operative relation to the other sections of the die, and be held stationary in such position during the compressing and shaping of the heel. The cam is also so shaped as to permit the lever to move the slide plate outwardly after the heel has been compressed, and to an extent sufficient to entirely withdraw the bed of the die from beneath the die cavity formed by the side sections and breast, and so that the molded heel within the cavity may fall or be moved downward into the space occupied by the bed during the compressing action and provided by its removal. This space may open into a recess in the upper part of the pressure head through which the molded heel may escape from the machine as represented in Fig. 7, or if the pressure head is not so shaped the slide plate upon its return movement will serve to eject the molded heel from said space to a position beyond the pressure head and as represented in Fig. 4.

A spring g6 attached at one end to the bracket slide g4, and at its other end to the bracket, serves to draw the bracket slide downward when the cam g permits an d to maintain the cam roll of the bracket slide in continuous contact with the cam. It likewise serves to move the lever y1 outward from the pressure head and therefore the slide plate forward and to the position represented in Figs. 2, 3, 5 and The slide plate Gr1 must have a bed forming portion of sufficient size to fully cover the die cavity which is necessary for receiving heels of the largest size. That portion of the way or space H in which it moves and which is beneath the die cavity must be wider than the widest space provided by such side die sections as are used for compressing the widest heels when they are wide open. The space H may be of any desired height exceeding that of a molded heel blank. ment to cause its inner end gl, to occupy a position in front of the inner faceof the breast section during the removal of the heel from the die, see Figs. 5, G and 7.

From what has been said it will be seen that the action of the compressing mechanism in shaping and compressing a heel blank is substantially as followsz-The heel blank having been placed between the side dies is held by the bed during the closing of the side sections against its sides, the breast section remaining stationary and the bed and side and breast sections having at the same time movement against the heel seat f ormer. This causes all the parts of the heel blank to be subjected to a compressing and forming pressure whereby it is provided with a heel seat` with a formed and compressed breast and sides and with a compressed and fiat tread.

`lt will be understood that the heel seat end of'a heel blank is always larger' than its tread end, and that the die cavity, when the side sections are closed, has its greatest area at the top and its smallest area at the bottom, and that if the side sections an d bed were not provided with specially designed movements the com- The slide plate should have a suicient movei pressed heel could only be removed from the die by being lifted upward with respect to the side portions of the die to a position above it from which it could be laterally moved away from it, or by being moved forward in line with the side sections by causing the breast section of the die to be movedvforward, and it is by mechanism designed to accomplish one or the other of these movements of the compressed heel fromv the side forming sections that the compressed heel has generally been removed from the die. Neither of these ways of removing the compressed heel from the dies has necessitated a wide opening of the side sections or of the die, or the removal of the bed which supported and formed one end of the heel.

My invention being designed to permit of the escape of the compressed heel from the side forming sections of the die by a downward vertical movement with respect to them requires that the bed forming the bottom of the die and heretofore never removed from beneath the die so as to thus open it and provide a heel receiving space beneath its cavity, shall be so constructed as to provide a bed for receiving and holding the largest heel which shall be compressed, shall be movable to open the die immediately after the completion of the compression of the heel blank and shall be returned to close the bottom of the die before the compression of the next heel blank in order, and shall also, when open, expose and form a space which shall be deep enough to receive from the die a compressed heel, which space shall be wider than the widest cavity o'f the die at any time, and which space shall also have an extension or outlet through which the compressed heel may escape or be moved from the machine; not only this, but the side compressing sections must also havefa length of movement suflicient to permit of heels, whatever the difference in size between their tread and heel 'seat ends may be, to pass or drop unimpeded by the flare of the side 'sections through the opening in the bottom which by their movement they have helped enlarge.

I have described the breast section as movable horizontally towards and from the side forming sections of the die. This movement of the breast section is not necessary for the purpose of permitting the molded heel to escape'or be moved downward vertically from the die, as above described, but is desirable when the slide G1 is also used as a means for feeding an uncompressed heel from a position in front of the compressing position to the compressing position. The breast section is then caused to be held stationary during the outward movement of the slide plate to permit the molded heel to be delivered from the dies, and it thus serves to prevent the molded heel from being drawn forward by the slide plate, (see Fig. 5,). Immediately upon the delivery of the molded heel from the die into the space II, the breast section is moved forward on the slide plate to occupy a position near its forward end, (see Figs. 2, 3 and and sufficiently removed from the side forming sections which are then wide open to provide ample space for the placing of an uncompressed heel upon the slide plate G1, and back of the face of the breast section F2, (see Fig. 6) the heel being placed upon the plate with its tread downward and its breast against the said breast section F2.

The breast section is held from moving forward with the slide plate G1 by means of its side extensions k, k1

-and the recesses k2, k3 upon the die slides f, f1. The

closing of these slides by means of the extensions and recesses causes the breast section to be locked to the sides and held locked during the compressing operation, and these recesses are of such depth that the breast section is not released from the slides f, f1 until the slides have very nearly reached the end of their outward movement and this does not occur until the slide plate G1 has been moved outward sufficiently to fully open the bottom of the die. This opening movement of the die slides f, f1 is occasioned by the downward movement of the pressure head supporting them acting through the links f2, f3, which are moved from a position approaching a horizontal one to a more inclined position, but the cam g controlling the movement of the slide plate G1 is so shaped as to permit the spring g to move the slide plate G1 forward more rapidly than the pressure head moves downward, and therefore the slide plate reaches the end of its movement or very nearly its end before the breast section j 2 is released. The breast section f2 is then immediately drawn forward upon the slide plate G1, by the spring m, which acts through a lever m1, pivoted at fm2, and

connected at its upper end to the breast section by the link m3. The breast section is moved forward until it comes into contact with the stop m4 at the front end of the slide plate G1, where it is held at rest Auntil the slide plate is moved inwarcL by its cam when the breast section is moved inward with it and of course drawing its operating lever m1 with it and compressing its spring m.

It will thus be seen that the breast section when thus moved furnishes in conjunction with the sliding plate G1 the means for receiving an uncompressed heel blank out of compressing position, and for feeding it from said position toA a compressing position between the side forming sections of the compressing apparatus, and upon the inward movement of the slide plate G1 the breast section is restored to a compressing relation with the side sections, an uncompressed heel is moved into a compressing position, the previously compressed heel if Astill in the space H is pushed outward from it, the space beneath the die cavity is closed and the die bed v of the die returned to a compressing relation with the other sections of the die.

The heel receiving chamber H may have the escape passage h extending from its end and having the inclined bottom h2 opening into the chute h1 as represented in Figs. 4, 5 and 6, or the chamber may be extended directly downward beneath the die as represented in Fig. 7.

The machine may be caused to fully stop at the end of each reciprocation of its pressure head and the compression and discharge of each heel, or it may be run continuously.

- When the invention is also employed for feeding uncompressed heel blanks its operation is as follows:- The operator places the uncompressed heel upon the slide plate G1 and against the breast section. ward movement of the slide plate and breast section feeds the heel to a position' between the side sections of the compressing apparatus, and if necessary moves from the chamber below the die cavity a previously compressed heel blank deposited therein. This inward movement of the slide plate and the breast section The in# los llO

brings into operative relation with the side sections oi the die and the heel seat ormer, the bed of the die and the breast, and it also brings the uncompressed heel into thecompressing cavity. The upward movement of the pressure head causes the side sections to be moved towards each other and the bed of the die towards the iormer, and the heel blank is thereby compressed by the conjoint action ol horizontally closing the sides and vertically closing the bed and iormer. This compressing action is immediately iollowed by thc downward movement oi the pressure head which causes the side sections. breast and bed to move lrom the former7 and also causes the side sections to be opened, and simultaneously with this movement the slide plate is drawn VIorward to open the bottom oi the die and the compressed heel drops or is ejected into the chamber H, which the withdrawal of the bed creates. The breast section is then released and moved forward and the slide plate and breast section then lorm a heel feeding means by which an uncompressed heel is fed horizontally directly between the side forming sections oi the die. When the breast section is ,not moved .the uncompressed heel is placed directly in the die cavity as soon as the compressed heel has been released therefrom and the bed oi the die returned to compressing position, when the pressure head must be given extra movement to provide the necessary space above the side forming parts oi the die. Any equivalent means to those described or holding the breast section and ior moving it and the slide plate G1 may bo employed.

Having thus fully described my invention, l claim and desire to secure by Letters Patent oi the United States 1. ln a machine for compressing heels, the combination oi a former, sectional dies for compressing the sides of the heel. movable from each other to enlarge the die cavity sullieiently to permit of the downward movement of the colnpressed heel through the die, a heel receiving chamber below the die cavity. and a die bed plate movable into and from said chamber and adapted when in said chamber to form a closed end to the die cavity.
